Description

n-(6-Aminohexyl)Rhodamine 6G-Amide Bis(Trifluoroacetate) is a high-purity, reactive derivative of the classic Rhodamine 6G fluorophore, featuring a primary amine linker for covalent conjugation. This compound matters for researchers and manufacturers requiring site-specific fluorescent labeling of biomolecules, polymers, and surfaces with a bright, photostable orange-red emission. It is essential for professionals in bioconjugation, diagnostics development, and advanced materials science who need reliable, well-characterized fluorescent probes.

Application

• Bioconjugation and Probe Synthesis: Covalent labeling of antibodies, proteins, peptides, and oligonucleotides via amine-reactive chemistry (e.g., NHS ester activation).
• Diagnostics and Assay Development: Used as a critical component in fluorescent immunoassays (FLISA), lateral flow tests, and in-situ hybridization (FISH) probes.
• Cell and Tissue Imaging: Preparation of fluorescent tags for tracking cellular uptake, receptor binding, and intracellular localization in microscopy.
• Polymer and Material Science: Incorporation into polymers, nanoparticles, and hydrogels to create fluorescently tagged materials for tracking and analysis.
• Flow Cytometry: Development of custom fluorescent reagents and antibody conjugates for cell sorting and analysis.
• Sensor Development: Key building block for constructing chemical and biological fluorescence-based sensors.
